Survival rates of Campylobacter jejuni ATCC 33 291, Campylobacter jejuni PZH 38 and Campylobacter coli ATCC 43 478 in leg quarters (ca 330g) of chicken broilers after microwave heating (480 and 760 Watt) for 2, 4, 6, 8 and 10 minutes were determined. Heating the meat in a microwave oven (Moulinex, type Dialog cook) at 480 Watts caused a gradual decrease in the number of cells of the studied bacterial strains to total inactivation after 8 – 10 minutes of heating. Increasing the heating power to 760 Watts led to a decreased microwave heating time of 6 – 8 minutes for inactivation of all the cells of the studied C. jejuni/coli strains. These findings clearly indicate the dependence of effectiveness of inactivation of the bacteria studied on microwave heating power, heating duration and bacterial strain.

In response to high temperature stress, plants express numerous small heat shock proteins (sHSPs) belonging to at least five related gene families. in vitro studies suggest sHSPs act as molecular chaperones to prevent irreversible heat denaturation of other proteins. The diversity of sHSPs in plants is unique among eukaryotes and makes it of interest to understand the origins of these proteins. sHSP-related proteins have now been identified in 13 prokaryotes, and in many of these prokaryotes the sHSPs are heat-regulated as seen higher plants. The prokaryotic sHSPs were analyzed by pairwise and mutliple sequence alignments with each other and with plant sHSPs. The higher plant class I cytosolic sHSPs are shown to be most similar to a subset of the prokaryotic sHSPs, including HSP 16.6 from the cyanobacterium Synechocystis. Genetic studies in this model cyanobacterium may provide insight into sHSP function in vivo, and into potential roles of sHSPs in higher plant cells.

Beauveria bassiana is an entomopathogenic fungus that is widely used in Thailand to control pest insects. However, the increasing temperature has influenced the insect control efficiency of the fungus. Therefore, determination of thermotolerant isolates of B. bassiana that can grow and remain pathogenic at higher temperatures than its current optimum temperature may be a better way to control pest insects in a high temperature environment. Three isolates of B. bassiana obtained from the Rice Department, Thailand were selected for mutagenesis using ethyl methanesulfonate (EMS) with subsequent screening at high temperatures (33 and 35°C). In addition, the recovery of fungal growth after exposure to a high temperature for a period of time (5–15 days) and then transferring to 25°C was evaluated. No isolates were found that grew at 35°C but one mutant isolate (BCNT002MT) produced larger diameter colonies and more spores than the corresponding wild type (WT) at 33°C. Growth and spore production of the BCNT002MT isolate were greater than its WT when incubated at 25°C for 14 days following exposure to 33°C for 7 days. In addition, the spore germination level (%) of BCNT002MT was significantly higher than its WT during culture at 25°C after prior exposure to 33°C for 5, 10 and 15 days. The pathogenicity against the brown planthopper, Nilaparvata lugens (Stål), of this mutant isolate was also prominent.

Hemolysis was used as an endpoint for the measurement of damage to the plasma membrane in human erythrocytes after a single or a double heat shock. The thermotolerance of erythrocytes is a transitional phenomenon, reaching its maximum at a 3-hour incubation at 37°C between the heat shocks.

Reactive oxygen species as second messengers? Induction of the expression of yeast catalase T gene by heat and hyperosmotic stress does not require oxygen

It is shown that oxygen is not absolutely needed for stress-induced synthesis of catalase T in the yeast Saccharomyces cerevisiae. Yeast cells develop heat resistance after exposure to elevated temperatures in anoxia. The levels of catalase activity and thermotolerance are comparable to those in aerobically stressed cells. While these results obviously do not exclude a stress signaling role of reactive oxygen species in some systems, as postulated by other authors, they suggest that the question of the obligatory requirement for reactive oxygen species in other stress signaling systems should be rigorously re-investigated.
